Apple M2 chips support the 6GHz RF(Radio Frequency) spectrum for Wi-Fi. If you don’t know what that means, then this post is probably not for you. However, if you do know your 2.4GHz from your 5GHz , then read on for some reverse engineering relating to; packet captures, custom bitmasks, and how to figure out which WLAN bands and channel widths are around your Mac (without having to use Apple’s CoreWLAN or clicking the Wi-Fi icon in the menubar).

TL;DR: IPv6 is faster than IPv4 ~39% of the time (locally anyway!). To answer this question we decided to look at anonymized data we had collected from a range of monitoring agents over a 30 day period. For simplicity, the data used only focused on the client’s RTT (Round Trip Time) to their default gateway.

TL;DR: IPv6 and IPv6 DNS often stops working on residential home routers. This can manifest in strange outages especially when your browser or computer continues to try using IPv6. Spot when this happens and fix it quickly by monitoring your IPv6 connectivity.
